Wiz Khalifa and Amber Rose’s Wedding Ceremony Happening This Weekend

Our friends at PopCrush just broke the news that rapper Wiz Khalifa and his fiancee, Amber Rose, will exchange vows at their wedding ceremony this weekend.

The couple, who have been dating since early 2011, signed a marriage license in July 2013, but have yet to hold an official wedding ceremony. A source exclusively told PopCrush that the celebration will be held in Khalifa's hometown of Pittsburgh.

In February, Amber Rose gave birth to the couple's son, Sebastian. Wiz told NYC radio station Hot 97 (via US Weekly) that the couple was waiting to hold the wedding until after Amber Rose lost some of the baby weight -- and so she can drink alcohol.

Earlier today (Aug. 15), Amber Rose posted a picture of her wedding dress on Instagram, noting that it takes one big box to transport the garment. "My wedding dress... Yea, it's that serious," she tweeted.
